SF4831 High Axial Load Bearings Sealed Angular Contact Bearings 240x310x33mm
Durable SF4831 Bearing For Excavators (240x310x33.4mm) - Ideal For Tough Working Conditions
Product Overview
The SF4831 excavator bearing is a high-performance bearing specifically designed for the complex working conditions of excavators. It plays a crucial role in ensuring the stable and efficient operation of excavators, and its outstanding performance makes it a reliable choice for numerous excavator manufacturers and the maintenance market.
Structural Design
Unique Contact Angle Structure
Adopts a 40-degree large contact angle design that greatly enhances axial load-bearing capacity. Effectively handles strong axial forces during excavator operations while dispersing stress to reduce failure risks.
Optimized Ball Configuration
Features more balls than ordinary bearings of the same specification, significantly improving overall load-bearing capacity and distributing pressure evenly to minimize wear and extend service life.
Durable Inner and Outer Rings
Made from high-quality bearing steel with special heat treatment processes for high hardness and excellent wear resistance. Precisely matched raceways ensure smooth rolling and stable performance.
Reliable Cage Design
Available in nylon (lightweight, low noise, self-lubricating) or steel (high strength, suitable for extreme heavy-load conditions) options to maintain stable ball rolling under harsh conditions.
Key Dimensions
Parameter
Value
Significance
Bore Diameter
240mm
Precisely adapted to excavator shaft diameter for tight fit, ensuring efficient power transmission and preventing vibration issues.
Optimized for structural strength and compact layout requirements, accommodating appropriate ball count while fitting limited installation spaces.
Weight
approx. 5.1kg
Balances strength for heavy loads with lightweight design to reduce inertial force, lower energy consumption, and improve equipment efficiency.
Performance Characteristics
High Load-Bearing Capacity
Basic dynamic load rating: 171kN; static load rating: 241kN. Capable of withstanding huge instantaneous loads without deformation or damage.
Excellent Self-Aligning Performance
Adapts to slight shaft deflection and misalignment, automatically adjusting to maintain normal operation and reduce additional stress and wear.
Long Service Life
Superior wear resistance and fatigue strength significantly extend service life compared to ordinary bearings, reducing replacement frequency and maintenance costs.
Low Noise and Low Vibration
Precision manufacturing ensures high matching accuracy, resulting in minimal friction, reduced noise levels, and enhanced operational comfort.
Application Scenarios
Excavator Travel System
Core component supporting entire machine weight and transmitting travel power. Handles impact loads from uneven ground and axial forces during steering.
Excavator Slewing Device
Bears huge radial and axial loads during slewing operations while ensuring stability and accuracy of slewing actions for precise positioning.
Other Key Components
Essential for working device connections (boom, arm, bucket) and hydraulic system rotating components, adapting to complex loads and frequent action changes.
